2 Claims.

The invention relates to improvementsA in supply containers for stripsin roll form and more particularly to a container adapted to house atleast two rolls of adhesive-coated strips and to adhesively join thestrips drawn from the rolls into a tear-resisting web of doublethickness for Ydelivery to an associated device operable to aix andattach patches severed therefrom onto sheets to be perforated.

The machine involving the features of the present invention is of a kindadapted to operate lupon the margin of a sheet of material, such aspaper, in such manner as to punch one or more holes therein. Duringmachine operation, and `iust prior to perforating the sheet, a patch ofreinforcing material is severed from a Isupply web and is adhesivelysecured to the sheet in the area of the perforation to be performed.Thus, when a sheet is perforated, the reinforcing patch likewise isperforated. As a result, the perforation in the sheet is reinforced toresist tearing out.

A device of the general character of the apparatus disclosed herein isshown and described in applicants copending application, Ser. No.36,157, led June 30, 1948.

The present invention distinguishes over the disclosure in thatapplication in various details of construction and principally in theconstruction of the containers mounted thereon.' each being adapted tocontain at least two strips of adhesive-coated material in roll form,which strips are adhesively secured one to the other during withdrawalfrom the container and prior to being fed to the perforating mechanism.

The machine illustrated herein is constructed in the form of a portablemanually actuable sheet perforating device, including pairs of severing,attaching and perforating elements. The ldevice illustrated is providedwith novel means to carry a plurality of rolls of adhesive-coated stripsof reinforcing material, of a kind commonly known as Scotch tape, andmeans to advance a double thickness of said material inthe form of aweb,4 step by step beneath said elements in such manner that portions orpatches thereof are severed therefrom and are axed to the sheet prior tothe perforating operation. The perforated portions of the web remainingare taken up on suitable spools so as to afford convenient means ofdisposal.

Accordingly, it is an object of the present invention to provide a noveldevice of the character described hereinabove.

Another object is to provide a novel structure adapted to house, formand deliver a yweb of adhesive-Coated material of double thickness to anassociated mechanism.

Another object is to provide a novelly associated web perforatingmechanism and supply container.

Another object is to provide a container for a plurality of rolls ofadhesive-coated tape with novel means to mount the container on asupporting Wall.

Another object of this invention is to provide a container of thecharacter described which is not diflicult or expensive to manufacture,which is easily mounted in position for use, and which is very efficientin operation.

Other and further objects of the present invention will be apparent fromthe following description and claims, and are illustrated in theaccompanying drawing which, by way of illustration, shows an exemplaryembodiment and the principles thereof. Other embodiments of theinvention embodying the same principles may be used, and structuralchanges may be made as desired by those skilled in the art withoutdeparting from the present invention and the purview of the appendedclaims.

Referring specifically to the disclosure in the drawing, the containersembodying the features of the present invention are, when in use,suitably associated with a severing, attaching and perforating device. tThe device, having the containers associated therewith, is bestillustrated in Figs. 1 and 2. As shown, the device includes asubstantially rectangular formed base H hav- Ying transversely spacedlongitudinally extending vupstanding walls I2.

3 with the base II or be otherwise firmly attached thereto.

A pair of cylindrical guides I3 is mounted in a vertical position, oneon the outside face of each wall I 2, substantially midway between theirends. Each guide I3 is adapted to contain elements for severing,attaching and perforating patches of adhesive-coated material affixed tosheets placed in a downwardly offset area I4 formed in the base I I andextending beneath the guides. The various elements carried within thecylindrical guides I3 are adapted to be reciprocated vertically byactuating means provided in the form of an operating handle I5 which ispivotally secured, inwardly of one end thereof, as at I6, to and betweenthe walls I2. A tension spring I1, normally connected at one end to thehandle I5 and at its other end to a tie rod I8, holds the operatinghandle elevated substantially as shown in Fig. 2;.

The operating handle I5 is effective, also, to actuate means for feedingthe webs of adhesivecoatedmaterial I9, step by step, beneath the guidesI3. rlLhis material is provided in roll form and in the present instancethe web IS consists of two thicknesses or strips of adhesivecoatedmaterial, each strip being in the form of a roll 2|, 2Ia, suitablycarried in a manner to be described in detail hereinafter within acontainer or housing 22.

It is sufficient to note at this time that two such containers 22 areprovided, one being detachably mounted on each of the side walls l2adjacent the rear ends thereof. The web I9, of double thicknessmaterial, is drawn from the container downwardly beneath a transverselyprojecting guide pin 23, then forwardly below the vertical guides I3 andaround the transversely projecting ends of the tie rod I8 from where itis carried upwardly to be wound around a rewind or takeup spool 24.

Step by step advance of the webs I9 beneath the vertical guides I3 isaccomplished through intermittent rotation of the take-up spools 24.These spools may be constructed in any suitable manner, and are carriedfirmly on transversely projecting ends of a rotatable shaft '25journalled in the walls I2 adjacent the forward upper ends thereof. Theintermediate portion of the shaft has a ratchet wheel 26 xedly securedthereon, Upon referring to Fig. l, it will be observed that theforwardly extending end of the operating handle I5 is forked, as at 21,to provide an opening through which the ratchet wheel 26 may project.forked portion 2 are turned downwardly and are suitably bridged by a dog28 which preferably consists of a strap having its ends resiliently heldto the downturned end portions, as by means of compression springs andpins 29.

It should be obvious at this time that when the operating handle I5 isswung downwardly to actuate the device, the dog 28 is carried upwardly.Owing to its spring mounting', the dog is held in position to engagebeneath one of the teeth-of the ratchet wheel 28, whereupon upwardmovement of the dog rotates the ratchet wheel a distance correspondingto the spacing between the teeth thereof. At this time the dog becomesdisengaged from the teeth. This spacing is such that the web I9 isadvanced a distance sulficient to locate an unperforated portion thereofbeneath the guide I3 after each successive perforating operation. Whenthe operating handle 1s permitted to return to its normal elevated Theextreme free ends of the .c

position, the spring-pressed dog 28 passes freely over the nextsucceeding tooth of the ratchet wheel 26 and is thereby positioned foragain engaging a tooth when the handle is next operated.

Means is provided to prevent backlash of the ratchet during the returnmovement of the dog. To this end, a leaf spring or finger 33 carried ona cross-rod 3| has itsv upper rolled end disposed for latchingengagement with the ratchet teeth.

As mentioned hereinabove, the operating handle I5 is adapted, also, toactuate the means for severing, attaching and perforating the web I9Vand a sheet of paper inserted therebeneath. Such means is bestillustrated and described in the copending application aforementioned,It is believed suicient, however, for the purposes of this disclosure,to note that each vertical guide I3 has a web severing sleeve 32reciprocal therein and adapted to be moved downwardly on initialdownward movement of the handle I5 so as to sever a circular patch fromthe web of material i9 lying therebeneath. Slidable within the severingsleeve is a circular pressing shoe or attaching ring 33 which isoperatively related to the severing sleeve 32 as to move downwardly,following the severing operation, to press the severed patch firmlyagainst and adhesively secure` it. tov thev underlying sheet.

The severing sleevev 32 and ring 33 are actuated in the manner aforesaidupon downward movement of a plunger 34 which is engaged by a transversepin 35 carried by the handle portion I5. This plunger has its lower endreduced in diameter so as to extend freely through the pressing shoe 33.Its bottom face is provided with a cutting edge so that upon continueddownward movement of the operating handle I5, after the severing andattaching operation has been completed, said plunger continues itsdownward movement to punch a circular opening through the attached patchand sheet.

As noted hereinbefore, each web of adhesivecoated material I9 isinitially contained within a container 22. Referring particularly toFigs. 3 and 4, the: container 22 consists of spaced apart side walls 4I, the bottom wall 42, end walls 43 and 44, and a top wall 45. A pair oftubular hubs 46 and 4l bridge the side walls I within the confines ofthe container. Each hub is adapted to have mounted thereon for freerotation a strip of adhesive-coated material ofsingle thickness in rollform. The strip |911 leading from the roll 2I is carried from the rolldownwardly across a transverse rod or roller 48, between knurlingrollers 49 to be hereinafter described in detail, and out of thecontainer through an opening 5I in the end wall 43 thereof.

It should be observed at this time that the roll 2| is of a kind havingthe adhesive-coated surface disposed outwardly so that the portion ofthe strip extending. between the rod 4B and the discharge opening 5I hasits adhesive-coated surface disposed downwardly. The other roll 2Ia ofadhesive-coated material is Wound in a similar manner so that itsadhesive-coated surface is disposed downwardly when the strip ISD iswithdrawn from the roll in the manner illustrated. As shown, this stripIb is carried in the directionof the rod 48 and is tensioned slightlythereby so that its top surface is 'brought into contact with and isadhesively secured to the bottom face of the strip I9a. In this mannerthe strips ISa and lsb, leaving the rolls 2l and. 2id, are adhesivelysecured together and pass out of the container in the form of a singleweb I9 of double thickness and consequently of double strength.

For a purpose to be better understood as the description proceeds, themarginal edges of the adhesively joined str-ips I9a and |91) may bepressed rmly together prior to their withdrawal from the container. Toaccomplish this, pressing means, preferably in the form of rollers 49,are provided. As best shown in Fig. 6, these rollers are carried onparallel shafts journalled at their ends in the side walls 4l and aresuitably held spaced apart by spacers 53 mounted on said shafts betweensaid rollers.

It is intended that containers of the kind described, with supply rolls2l and 21a enclosed therein, be furnished to users of the device.Accordingly, means is provided on each container and on the device forcooperative association to afford means whereby the containers may befirmly and securely mounted in position quickly. Such means on thedevice preferably consist of the longitudinally spaced verticallydisposed slots 54 and vertically aligned projections formed in each ofthe side walls l2.

One of the container walls 4| is provided with longitudinally spacedpairs of vertically aligned projections 56 and 51. The projections 56preferably consist of struck-out lugs adapted to be engaged in the slots54 when the container is held in contact with the wall upon which it ismounted. The other pair of projections 51 preferably consists ofstruck-out pairs of ears adapted to engage over the wall projections 55when the container is mounted. To mount a container, the lugs 56 areinitially inserted into the slots 54. With the container held elevatedso as to locate the lugs 56 at the upper ends of the slots, the ears 51are aligned with the projections 55. The container then is moveddownwardly into the position shown in Fig. '7, with the ears engagedover projections 55.

It should be quite evident that a loaded container may be easily andquickly mounted in place and, when empty, may be removed withoutdifliculty.

The rewind spools 24 are, as mentioned hereinbefore, firmly mounted uponthe transverse ratchet shaft 25. Inasmuch as the specic structure ofthese spools forms no part of the present invention, it is suliicient tonote at this time that each is provided in one of its walls with asquared opening 58 to fit snugly the squared end of the ratchet shaft 25when mounted in place thereon.

When the web of adhesive material has been perforated, the areasurrounding the perforation becomes stretched. Such stretching isminimized by the firm adhesion of the marginal edges of the stripsconstituting the web. Consequently, perforated web wound upon the rewindspools 24 will lie substantially fiat without undue bulkiness orbulging.

Although an exemplary embodiment of the present invention has beendisclosed in detail in the accompanying drawing and has beenspecifically described in the foregoing specification, it should beunderstood that the structure as a whole is capable of embodying a widevariety of modifications in detail and that the device as a whole,including the containers and spools, may be enclosed within a suitablecover or casing. Also, the containers may be of a size to accommodatethree or more strips in roll form so as to facilitate the feeding of atape of triple or greater strength. It should be further understood thatthe improved container herein disclosed may be utilized in associationwith reinforcing and perforating devices of a character other than thatdescribed, all without departing from the spirit of the invention or thescope of the appended claims.

I claim:
